We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

What drives investors' attention? We study how far in advance earnings calendars are pre-announced and find that investors are more attentive to earnings news when such details are disclosed well ahead of time. This variation in investors' attention affects stock prices, thereby creating...

Prior analyst literature focuses on the impact of financial analysts on the firms they cover, and prior information-transfer literature concentrates on the externalities of information provided by management. This paper fills gaps in both streams of literature by examining the focal firm's...

Information processing filters out the noise in data but it takes time. Hence, low precision signals are available before high precision signals. We analyze how this feature affects asset price informativeness when investors can acquire signals of increasing precision over time about the payoff...

This paper investigates the extent to which voluntary disclosure quality (VDQ) of firms is reflected in equity prices. As a novel contribution, we explore the idea that the speed with which equity prices reflect any benefits or costs of VDQ varies across firms. We find that in environments where...

This report updates and expands earlier studies to look at the profitability of $349.7 billion of buybacks executed from 2000 through early 2010 by a sample of 275 corporations. The sample companies, drawn mainly from the technology sector, enjoy total equity market value today of $945.6...

This study seeks to regress the forward P/Es on firms' fundamentals as measured on global market basis. Starting from theoretical premises (DDM), the paper develops a linear multivariate model in order to capture (for US, Australia / New Zeland / Canada, Europe, Japan and Emerging Markets quoted...

This paper examines stock price formation subsequent to management forecasts of quarterly earnings. In the post-announcement period, we find a significant upward price drift for both good news forecasts and bad news forecasts. Combined with the asymmetry in the initial market response, the...
